Someone help... pleaseee
frutty [35]

Answer:

2x + 8

Step-by-step explanation:

Don't worry, this is simple! Add up the common terms.

For example, you can't add up 2x and 5, because 2 is being multiplied by a variable.

So combine the x terms: 2x

And the numerical terms: 8

Combine 2x and positive 8.

2x + 8
